Do my girls actually care for me?

My little goobers really don’t have too much of distinct personalities. In terms of shyness, they’ll excitedly line up and take treats from my hand, but that’s about it.

They never let me touch them in the cage and when I take them out for lap time they just freeze, not really caring where and how I pet them.

Just, they’re not nearly as ‘people pigs’ as most other pigs here despite having been here for almost a year
